Answer:
1. Character
2. Trait
3. Monohybrid cross
4. Alleles
5. Dominant allele
6. Recessive allele
7. Phenotype
8. Genotype
Explanation:
1. Character is an inherited feature passed through genes that varies in individual e.g flower colour
2. A trait is the variant form of a character e.g red and blue flower colour are variant forms of the flower colour character.
3. Monohybrid cross is a cross between two parents differing in only one character.
4. Allele is an alternate form of a gene e.g A and a alleles for gene A
5. Dominant allele is one of the allelic pair that expresses itself by masking the expression of the other allele in a heterozygous state.
6. A recessive allele is the allele that is masked or not expressed in a gene. It is covered up by the presence of the dominant allele.
7. Phenotype is the physical and visible trait of an organism e.g Tallness, colour
8. Genotype is the genetic constituent of an organism e.g AA, Aa etc.

The Endoplasmic reticulum is the organelles that is involved in the synthesis of oils.
<u>Explanation:</u>
The endoplasmic reticulum is of 2 types that is the ''smooth endoplasmic reticulum'' and the ''rough endoplasmic reticulum''. The rough endoplasmic reticulum is lined with ribosomes whereas the smooth endoplasmic reticulum is plain.
Since ribosomes are present the rough endoplasmic reticulum is involved in protein synthesis whereas the smooth endoplasmic reticulum is involved in the production of oils or lipids that are required for the cell.
